I was moving around this guy, taking pictures — he never blinked (get it? Yeah, I’m sure my daughter’s rolling her eyes).
A runner who’d been out running the Greenland Open Space approached, and I wanted to stick around long enough to prevent her from stepping on it. I don’t know for certain, but I think this guy was getting ready to moult; I’ve read that their vision and overall reactions are diminished during that time frame. Or perhaps he just wasn’t bothered.
